In present paper, densities and viscosities of pure butyl acetate, 2-propanol, 2-butanol, 2-pentanol, and their binary mixtures with butyl acetate were measured at temperatures 293.15 to 323.15 K. From these data, excess molar volumes and deviations in viscosity have been calculated. Excess molar volumes are positive over the whole concentration range and increase with rising temperature. Viscosity deviations show negative values for all studied mixtures and increase as temperature increases. The ability of Peng–Robinson (PR), Peng–Robinson– Stryjek–Vera (PRSV), SAFT and PC–SAFT equations for correlation of the volumetric properties was tested. The liquid density of the binary mixture was obtained more accurately by both SAFT and PC–SAFT models with the maximum AAD 0.082% and 0.041%, respectively. Prediction of excess molar volumes by PR and PRSV equations is closely matched with the experimental data with the maximum AAD 1.12% for PR and 0.087% for PRSV model.
